I had one go until 37 miles shy of 275,000. It was my '84, it was given to me with 257K on it and I drove it a couple years daily. I replaced the original clutch and threw in an aluminum flywheel while I was in there and it spit an apex seal a week later.

280K on 1985 GSL-SE. Original engine, no major work, although the transmission probably won't make 350K...

HMMM...This is all good news. I new these engines were good! I think I can rest assured that my 100,000 mile engine should last a bit longer.

Yeah, the N/A 12a is bulletproof.

The turbo 13b got more fragile as they pushed the limits further in the later models. Stock 3rd gens typically lose their engines pretty quick.

Hey Jon...I pm'ed you a few months ago about a surging problem I was having with my car...do you recall? I am near Pembroke....

280,000 '84 GSL-SE original engine.

Original 12A in my 83 was warped due to excessive overheating at 153K. I bought the car that way and a used 84 12A to put in her. Not sure on the mileage there but it blew an apex seal after 4 years. I only put about 44K on that engine because the chassis was at 197K. I spliced her a few months ago with an 82 that had 148K on her. She's still going strong with the donor organs. I kept the original motor and tranny (which is still good) in order to get matching #'s on her again one day...Maybe I'll rebuild that 84 12A with the blown apex. Hmmm....another day, another project. LOL

Mine had 211k on it when it finally popped. It had 70psi compression front, 55psi rear, about 5k before it let go.

I only overrevved it a bunch of times and pegged the temp gauge about six or seven times when the heater hose would blow out or the radiator end tanks would pop, so it should have lasted a bunch longer It sometimes would use coolant when cold, but sometimes not.

The weekend before it died I was running it about 7-8k around the rallycross course, letting off a bunch to keep it below 8k! It also boiled over and ran funny on the way home. It led a hard life.

Oh - and no dowel pin leakage despite having the beehive oil cooler.

My friend's '79 had 60k on a MANA rebuild when that let go. From what I understand, that is remarkably long for a MANA It has a Series 3 12A in it now with some "goodies"...

I have 96,300 on my 82. I just got it last week and it have put about 200 miles on it. Had to show it off to all my friends

Spyride

Got my car about 6 months ago at 145k now its has 147k and is still going good doing DD and autocross duty. and it has a turbo kit in the works. Im confident that it will hit over 200k even with the boost and still doing autox's. But Both are close to my house.
